YES and No Yes if you are going to be working on the gas water heater and No if you are working on a cold water line and if you are working on a hot water line you can shut off the gas or electric to the water heater so in case your water heater drains but what I usually do is just turn the water heater's water supply valve off.
If your modular home has a regular gas supply that is a satisfactory way to do it.
